SPECIFICATION forming part of Letters Patent No. 533,137, dated January29, 1895.

Application filed July 13, 1893- Serial No. 480,333. (No model.)

To all whom it may concern:

Beit known that I, CLARENCE O. MULFORD, a citizen of the United States,residing at Streator, county of La Salle, and State of Illinois, haveinvented certain new and useful Improvements in Steam-Generators,ofwhich the following is a specification.

Referring to the accompanying drawings, wherein like reference lettersindicate like parts, Figure 1 is a vertical section of a boiler and domeshowing my improvement, and Fig. 2 is a similar section at right anglesto Fig. 1.

My invention is designed to prevent the passage of water into the steampipes, and consists in the peculiar construction of the steam domedescribed, by means of which this result is secured.

At the top of the dome F, is constructed a port (or ports), from whichthe pipe conducts the steam to the engine or other desired point. Insidethe dome and constructed integral therewith a cylindrical collar (orcollars) h encircles the eduction port and extends downward into thesteam space. Any water which by reason of agitation, foaming, or bycondensation, aided by the current of steam, tends to creep toward andenter the eduction port and the pipes, is arrested by the collar. Thecollar extends downward and draws the supply from what is termed the drysteam which occupies the dome. This is very important, as in many casesso much water enters the pipes as to seriously interfere with thepassage of the steam. It is thus carriedinto the cylinder of the engine,or intothe pipes, and often with serious results.

passage of water from the boiler into the steam pipes, as theseadvantages are well.

known and understood by those skilled in the use of steam.

It is obvious that two collars, one larger and encircling the smaller,may be used if preferred, but ordinarily a single collar as shown in thedrawings is sufficient.

I am aware of the patents to food and Richmond, No. 294,300, datedFebruary 26, 1884; to Frick,No. 331,488, datedDecember 1, 1885, andEnglish patent to Brown, No. 11,600, dated July 20, 1889, and I do notclaim the inventions therein set forth.

.What I do claim, and desire to Letters Patent, is-

1. In a steam boiler, the herein described steam dome having acylindrical collar, integral therewith, surrounding the eduction portand extending inwardly into the steam space, substantially as and forthe purpose set forth.

2. In a steam boiler, the herein described steam dome constructed in asingle piece and having one or more cylindrical collars, constructedintegral therewith, surrounding the eduction port and extending inwardlyinto the steam space, substantially as and forthe purpose set forth.
